  1. Greengiant, that old Brock looks fantastic! Can't wait to see it in person.Maybe someday I'll see if I can set up a time to stop in and check it out if you would be so inclined. Just love these oldies brought back to life again.

  2. hI,with some of our first CH models with V Mack 1 we had problems with the wiring harness where it went behind the windshield washer bottle. The wires would rub bare and short out. This is the harness that goes from the cab to the pump harness.Just a thought, might want to check. thanks, Steve

  3. Hi, I think it is a good idea to clean out the cooler. In the past I have used Dawn or Joy and lots of hot water to flush them out. The oil and gunk in the cooler insulates it and the heat exchange is lessened. Of coarse you should remove the cooler to do this. Good luck, Steve

  4. Trey, I'm partial to the Fontaines.They have a positive lock with the bar that slides behind the pin. They are easy to rebuild, no welding and grinding. The new ones are cast steel instead of stamped so the Holland fans may be more apt to try. Easy to adjust for wear.My choice by far. Steve

  5. Hi, my friend tells me the oil bleeds briefly when dynatard is first applied from port at base of solenoid. Thought that was odd so checked another E7 that he was retorqing heads on, same thing. We thought oil bled when solenoid was released not applied. We wre looking for a diagram of oil flow in dynatard.couldn.t find one. I will check old service bullitens tomorrow for any info. This was a Mack pedigree reman that he rebuilt after only 160K miles.He used OEM parts including heads. Thanks, Steve

  6. Hi, a friend just rebuilt a mechanical E7 350.This man is a fine mechanic who has an excellant reputation of being the best.He did an inchassis with piston and liner kits, rod and main brngs, pump and injectors and rebuilt heads. When the engine brake is turned on it works fine but when it is shut off one cylinder on no.1 head stays on until the oil pressure drops.He changed the dynatard solenoid, still did it. Thought maybe an exhaust hydraulic lifter was sticking,went thru and reset.Switched complete rocker from front to back, problem stays in front head. will do this when brake is manually applied with no electrical power, so not an electrical issue. Yes oil is at operating temp, truck driven several miles. Any ideas?Thanks,Steve

  7. In 1982 we bought a 1979 Superliner with an 8v92 430 hp. This was factory, an RWL770LST. As depicted by the L it did have an aluminum frame. This was about 220" w.b. and had a 36" sleeper. It had a Spicer SST14 air shift. We used it for many years and now a farmer down the road has it.Thanks, Steve

  8. Hi,you don't want to try to straighten the harmonic balancer and you sure shouldn't run the engine with a bad one.These have a ring inside that is free to turn to balance the pulses and vibrations. A bent one will cause damage to the engine.Another one doesn't have to be balanced to the motor, but these will were out over time and the ring won't turn inside.You can tell if you put on a bad one, the fan belts will throw off. Good luck,Steve
